Examples
The example shows how to select a complicated area of an image using Magic Wand tool and the ability to interact with masks (invert, union, substract).
var imageFilePath = "input.png";
using (RasterImage image = (RasterImage)Image.Load(imageFilePath))
{
image.MagicWandTool.Select(new MagicWandSettings(845, 128));
image.MagicWandTool.Union(new MagicWandSettings(416, 387));
image.MagicWandTool.Invert();
image.MagicWandTool.Subtract(new MagicWandSettings(1482, 346) { Threshold = 69 });
image.MagicWandTool.Subtract(new RectangleMask(0, 0, 800, 150));
image.MagicWandTool.Subtract(new RectangleMask(0, 380, 600, 220));
image.MagicWandTool.Subtract(new RectangleMask(930, 520, 110, 40));
image.MagicWandTool.Subtract(new RectangleMask(1370, 400, 120, 200));
image.MagicWandTool.GetFeathered(new FeatheringSettings() { Size = 3 });
image.MagicWandTool.Apply();
image.Save(outputFilePath);

Here's a more complete example with multiple lines of code inside the method:
public byte GetByteOpacity(int x, int y)
{
var maxX = this.Width - 1;
var maxY = this.Height - 1;
if (x < 0 || x > maxX || y < 0 || y > maxY)
return 0;
}Parameters

I have only re-formatted the given C# code to follow standard conventions:
- Modified or removed code comments
- Rename any variables, methods, classes, or types
- Change or remove namespaces or fully qualified type names (e.g., Aspose.Words.CheckBox)
- Alter logic or behavior in any way
- Add any output beyond the raw C# code — no code fences (e.g., ```csharp), no explanations, and no conversational text
- Assume any library-specific knowledgeParameters
